Hi All,
I have wondered if in the frit making process whether or not one could make
a sacrificial clay crucible to be ground up along with the melt inside the
crucible. This may only be applicable to batch compositions that call for
the silica/alumina that would be provided by the clay crucible, and in the
same quantities by weight.
I do forsee that there may be a problem if the amount of silica/alumina
required of the batch is less than would be necessary to form a crucible
capable of containing the melt without failing during the melting process.

It's my understanding that part of the frit making process is to pour the
molten material from the crucible into water (all together now: "safety
glasses on everyone"). Why now grind up the crucible? The frit is in the
water and the crucible isn't.
